|
|

|

|

|

|
|
|
+ The `-ansi' switch to the GNU C compiler, and standards conformance
|
|
|
+ options such as `-std=c99', define __STRICT_ANSI__. If none of

|

|
+ to have _POSIX_SOURCE set to one and _POSIX_C_SOURCE set to
|
|
|
+ 200809L, as well as enabling miscellaneous functions from BSD and
|
|
|
+ SVID. If more than one of these are defined, they accumulate. For
|
|
|
+ example __STRICT_ANSI__, _POSIX_SOURCE and _POSIX_C_SOURCE together
|
|
|
+ give you ISO C, 1003.1, and 1003.2, but nothing else.
|
|
|
+
|
|
|
+ These are defined by this file and are used by the
|
|
|
+ header files to decide what to declare or define:
|
|
|
+
|
|
|
+ __GLIBC_USE (F) Define things from feature set F. This is defined
|
|
|
+ to 1 or 0; the subsequent macros are either defined
|
|
|
+ or undefined, and those tests should be moved to
|
|
|
+ __GLIBC_USE.
|
|
|
+ __USE_ISOC11 Define ISO C11 things.
|
|
|
+ __USE_ISOC99 Define ISO C99 things.
|
|
|
+ __USE_ISOC95 Define ISO C90 AMD1 (C95) things.
|
|
|
+ __USE_ISOCXX11 Define ISO C++11 things.
|
|
|
+ __USE_POSIX Define IEEE Std 1003.1 things.
|
|
|
+ __USE_POSIX2 Define IEEE Std 1003.2 things.
|
|
|
+ __USE_POSIX199309 Define IEEE Std 1003.1, and .1b things.
|
|
|
+ __USE_POSIX199506 Define IEEE Std 1003.1, .1b, .1c and .1i things.
|
|
|
+ __USE_XOPEN Define XPG things.
|
|
|
+ __USE_XOPEN_EXTENDED Define X/Open Unix things.
|
|
|
+ __USE_UNIX98 Define Single Unix V2 things.
|
|
|
+ __USE_XOPEN2K Define XPG6 things.
|
|
|
+ __USE_XOPEN2KXSI Define XPG6 XSI things.
|
|
|
+ __USE_XOPEN2K8 Define XPG7 things.
|
|
|
+ __USE_XOPEN2K8XSI Define XPG7 XSI things.
|
|
|
+ __USE_LARGEFILE Define correct standard I/O things.
|
|
|
+ __USE_LARGEFILE64 Define LFS things with separate names.
|
|
|
+ __USE_FILE_OFFSET64 Define 64bit interface as default.
|
|
|
+ __USE_MISC Define things from 4.3BSD or System V Unix.
|
|
|
+ __USE_ATFILE Define *at interfaces and AT_* constants for them.
|
|
|
+ __USE_DYNAMIC_STACK_SIZE Define correct (but non compile-time constant)
|
|
|
+ MINSIGSTKSZ, SIGSTKSZ and PTHREAD_STACK_MIN.
|
|
|
+ __USE_GNU Define GNU extensions.
|
|
|
+ __USE_FORTIFY_LEVEL Additional security measures used, according to level.
|
|
|
+
|
|
|
+ The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
|
|
|
+ defined by this file unconditionally. `__GNU_LIBRARY__' is provided
|
|
|
+ only for compatibility. All new code should use the other symbols
|
|
|
+ to test for features.
|
|
|
+
|
|
|
+ All macros listed above as possibly being defined by this file are
|
|
|
+ explicitly undefined if they are not explicitly defined.
|
|
|
+ Feature-test macros that are not defined by the user or compiler
|
|
|
+ but are implied by the other feature-test macros defined (or by the
|
|
|
+ lack of any definitions) are defined by the file.
|
|
|
+
|
|
|
+ ISO C feature test macros depend on the definition of the macro
|
|
|
+ when an affected header is included, not when the first system
|
|
|
+ header is included, and so they are handled in
|
|
|
+ <bits/libc-header-start.h>, which does not have a multiple include
|
|
|
+ guard. Feature test macros that can be handled from the first
|
|
|
+ system header included are handled here. */
